King is more concerned with the attitudes of "white moderates" than he is with those of outright enemies of integration such as the Klu Klux Klan because the "white moderates" they are more devoted to order than to justice. They claim to be part of solutions to race relations yet do nothing to change the racist system. Their lack of action makes them complicit to the injustices against Black Americans.
